FORM FOR MAKING CUR/BS.

Application filed J 1115 13, 1914. Serial 0. 850,726.

To all whom it may concern:

Be it known that I, FRANKLIN W. ESOHEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Forms for Making Curbs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in molds for makingconcrete curbs and comprises a simple and efiicient device of this nature so arranged that it may be easily and quickly set up and taken apart.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view showing a portion of my improved mold or form set up for use. Fig. 2 is a cross sectional view showing the division plate adjusted in place. Fig. 3 is an enlarged detail perspective showing the means for holding the channel plates together, and Fig. 4 is a detail view of the locking key.

Reference now being had to the details ofthe drawings by letter, A designates the rear plate of the mold, -made preferably of iron, having flanges A along its opposite edges, said flanges being provided with slots B at different intervals, and slots C are also formed in the walls of the plates.

The front face of the form or mold is composed of two series of channel plates, designated respectively by letters D and E, each having an upper flange F with slots F therein said plate E also having a lower flange. The upper series of said channel plates D has flanges only upon the upper edges and which are slotted for-the reception of a key H which passes also through a registering slot in a plate I fastened to the flange of an adjacent section. Secured to each upperfiange of 'a lower plate E Specification of Letters Patent.

is a locking plate J, slotted as at J for the reception of a key K which also passes through a slot in a flange at the upper edge of the rail. Straps O are fastened to the face of each upper front channel plate and each is adapted to receive the locking tongue J which is integral with and projects up ward from the locking plate J. The adjacent ends of the channel plates E are held together by means of a tongue N upon one plate which engages a strap N upon an adjacent plate.

Division plates, designated by letter S, are provided withdownwardly extending'lugs S upon either side thereof adjacent to the upper end of the plate, while similar lugs T project on opposite edges of the plate adjacent to its lower ends. The said lugs S are designed to engage one or another of the. oppositely disposed slots B and F, formed respectively in the flanges at the upper ends of the plates A and F, while the lugs T engage slots R formed in the lugs R which are integral with the locking plates R said lugs R being adapted to be passed through one or another of the slots C formed in the plate E.

Angle members W are fastened to the lower front section E and are vertically disposed and are provided for the purpose of keeping the upper section D in a line and also acting as guides to keep the same in position, said angle member W passing through aslot in the flange of the section E.

By the provision of a form or mold made in accordance with my invention, it will be noted that the length of the curb may be determined by placing the division plates in various slots in the flanges along the opposite walls of the mold, the partitions being securely held in the manner described, while.

the channel lates are also locked and held securely. A ter the curb has been molded, the locking keys may be easily and quickly removed, which will allow the plates to be taken down.

What I claim to be new is 1. A form or mold for making curbs consisting of a plate having slotted flanges upon its opposite edges and forming one wall of j the mold, superimposed flanged plates and means for securing the same together and forming the opposite wall of the mold, the flanges of the upper of said plates being slotted, and slots formed in the walls of the oppositely disposed plates, division plates having upon their opposite edges lugs parallel with the length thereof adjacent to the top and bottom of the plate and adapted to engage slots in the flanges of the plates, key plates having lugs passing through slots in the wall plate and slotted for the reception of the lugs upon the division plate.

2. A form or .mold for making curbs consi'sting of a plate having slotted flanges upon its opposite edges and forming one -wall of the mold, superimposed flanged plates and means for securin the same together and .forming the opposite wall of the mold, the

flanges of the upper of said plates being slotted, slots formed in the walls of the oppositely disposed plates, division plates having upon their opposite edges lugs parallel with-the length thereof adjacent to the top and bottom of the plate and adapted to engage slots in the flanges of the plates, key plates having lugs passing through slots in the Wall plate and slotted for the reception of the lugs upon the division plate, locking plates secured to the flanges of the under of the side channel plates and overlapping the end of the flange of an'adjacent plate, the overlapping portion of the locking plate being slotted, a key passing through registering slots-in the locking plate and flange, a lug projecting from each locking plate, and a strap engaged by the lug.

In testimony whereof I hereunto affix my signature in presence of two Witnesses.

FRANKLIN W. ESCHEN.
